Mobile Set (MS) positionig issues, near to GPS level

| Hi there all!
I m new to this group as well as to the field of communication.
(1) My Big Question is "Can we calculate the the GPS type of MS
location?"
(2) I think this could be done when the MS asynchronously (near to
synchronously, sending the information such as GPS location quantities
to the BTS, during idle mode?
Kinldly help me in understating these things?

Phase II Wireless E911 Technology Choices
As of May 2003, here are the methods being used by the largest wireless
carriers to provide Phase II service:
Carrier Network
Technology Phase II Technology Type
T-Mobile GSM E-OTD* network
Nextel iDEN A-GPS handset
Cingular TDMA-GSM E-OTD* network
AT&T Wireless TDMA-GSM E-OTD* network
Verizon CDMA A-GPS/AFLT handset
Sprint CDMA A-GPS/AFLT handset
Both Cingular and AT&T Wireless are phasing out their TDMA networks.
* In Oct. 2002 Cingular and AT&T Wireless notified the FCC that it was
halting E-OTD development because they were uncertaint that
the technique could meet the accuracy requirement by the Commission's
deadline. In March 2003 T-Mobile also told the FCC
it would stop deployment of E-OTD gear. The carriers said they would test
U-TDOA technology to provide Phase II service.

Cingular Switches to U-TDOA for E-911 Positioning
Date Posted: Dec 17, 2002, 12:25 AM Source: Wireless Week
Cingular has decided to switch technologies for meeting the FCC's
E-911 mandate for locating 911 callers. Cingular has told the FCC
that after completing successful field trials involving
TruePosition's network-based U-TDOA technology, it was moving away
from E-OTD, which so far has failed accuracy tests, resulting in
delays and financial penalties. Cingular in October suspended
shipments of E-OTD gear and began testing TruePosition's solution.
